One more thing. I'm using "Volkov Commander" file manager (something like Norton Commander). When I press Up or Down button in the old "ykhwong 20150125 Dosbox" build, the cursor starts moving immediatelly up or down direction. But the same action either with the "DOSBox r4454" or "DOSBox ECE r4454" …

Hello. Just made the test of old "Mach 3" game (dos, 1987). With "DOSBox r4454" the sound (pc speaker emulation) is fine, but with "DOSBox ECE r4454" it sounds louder and with noise/cracks/clicks. Windows 7 user.

the F10 button does not work properly - when I press F10 the emulation stops and I get into the GUI (tested with win98/XP RUS)
